High Concept : "Wandering Amnesiac Sorcerer"
Trouble: "I dont try looking for trouble it seems to find me just fine"
Other Aspects: "
"Misery Loves Company" Trouble has a way of finding me
"My memory is like a still pond, empty and devoid of all life, until you disturb its surface"
"My Gold Wedding Band"
"Where did I come from?, Who am I? Why can't I remember? What have I done to have so many people wanting to hurt me? How did I come to be without my Memory"
"If I could only remember who I am"
Some of your aspects are a little too long, when I come up with aspects I like to try and keep them pithy and punchy. For your Trouble I'd shorten it to
"I'm Not Looking For Any Trouble." All the rest of it is nicely implied in that phrase, especially with some of your other aspects.
"Where did I come from?, Who am I? Why can't I remember? What have I done to have so many people wanting to hurt me? How did I come to be without my Memory" Is way too long, it will be insanely hard to fit on a character sheet if nothing else, try something like
"I Just Want Some Answers.", or maybe
"I'm Looking For Answers!" which embodies most of those questions and also might be invoked for a bonus when the character sticks his nose where it doesn't belong, and ties in nicely with the character's trouble.
You've also loaded up on quite a lot of memory loss Aspects and now a lot of those compels and issues can be handled with your High Concept, and one or two aspects. The aspect
"My memory is like a still pond, empty and devoid of all life, until you disturb its surface" is very cool and evocative it could almost be split into two or three aspects, but what do you want this aspect to do in the game? It seems like your going for something along the lines of having great power inside that can be unleashed when it is least expected. Some more aspects about your magical powers are probably in order so perhaps something like
"Don't Make Me Angry!", or for something less Incredible Hulk;
"Unexpected Talents",
"Hidden Depths of Power",
"Deep Reservoir of Power",
"Power Beneath the Surface",
"Still Waters, Run Deep". Really though it depends on what you think it means and how you want it to effect play, I'd just suggest an aspect dealing with the character's magic power might be more useful than yet another memory based aspect.
"Misery Loves Company" and
"Golden Wedding Band" are both good, and they are short and to the point, I'd be curious how you're thinking you might invoke the first one, do you make friends who get into trouble with you, or that you end up sharing in their troubles? Or are you really going to mainly compel it help to pile on the pain, and invoke it to be inured to suffering. Also you could tweak the second one to point it a direction that really interests you with not much more than the addition of a word and a question mark "
A Golden Wedding Band?" is quite different from
"My Golden Wedding Band?" or
"Who's Gold Wedding Band?", punctuation can really make a big difference in Aspects and exclamation points and question marks can be great additions to some Aspects.
"If I could only remember who I am" Since you've already got a lot of general memory loss aspects I'd be inclined to make this one much more pointed and focused.
"Am I Wanted By The Wardens?",
"Why Can I Remember The Laws?",
"Why Can I Remember The Name ____?",
"Should My Past Remain Hidden?". The character's wanting to remembering who he is is already taken care of. Throw him a bone and give him a clue that can be pursued during play, or maybe just go with a useful utility aspect like
"Magic Isn't The Only Thing I Remember How To Do",
"I Remember More Than Magic", or
"I Might Know How To Do That".
Powers (Sorcerer Template)
Evocation (Air, Earth, Spirit)
Ritual (Spirit)
So choosing a Ritual specialization works a little differently than Evocation, you don't pick an element rather you pick one Type or Theme of Thaumaturgy. You should take a look at Types of Thaumaturgy beginning on YS page 274, Thematic Thaumaturgy on beginning on YS page 284 to get a sense of potential options. Themes are broader based in terms of powers essentially letting you use all the Types of Thaumaturgy, but they are based only on specific applications of those powers. Ritual (Ectomancy) can do all the types of Thaumaturgy, but only if they deal with ghosts. Whereas Types of Thaumaturgy are very specific powers which can be applied in a broader way. Ritual (Summoning and Binding) for instance can be used to Summon and Bind just about anything, not just Ghosts, but it couldn't be used to Veil or Craft.
Since you've put down Ritual (Spirit) it seems like you'd like to have more of a Themed Thaumaturgy, I'd suggest either Ectomancy or Psychomancy. Psychomancy could be really neat for this character especially if you want to walk that razor's edge of Lawbreaker, and also delve into the recesses of his own mind. Otherwise if you want more of a Type of Thaumaturgy for your Ritual: Divination, Veils, or Summoning and Binding, are pretty solid choices that fit the Spirit element choice pretty well.
Wizards Constitution
The Sight
Soulgaze
Since you already picked up Soulgaze for free when you got The Sight you are now just one Major Milestone away from being a full Wizard.
As for the Norse god I am not sure where to begin, I was guessing kinda like an example someone found an old stone hammer and BAM! became an emmisary of power for Thor. But the directions aint exactly step by step on how to do it.
Start with a High Concept that deals with being "Thor's Emissary", and start buying powers like Marked by Power, and Item of Power if you want to go the "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor." route. Then it is just a matter of picking out the powers that the Item of Power grants and applying the Item's discount. For Thor's powers and depending on Refresh levels, at low levels it would probably grant Inhuman Strength, Inhuman Speed, Inhuman Toughness and/or Inhuman Recovery, it might also have Breath Weapon to handle throwing Lightning Bolts. At higher levels increase it to the Supernatural or maybe even Mythic levels of those powers, and possibly add Sponsored Magic (Storm God). It will also be indestructible by normal means and be a (Weapon:2-3), it may give some +1 or +2 Stunt-like bonuses in certain instances, and might also have the ability to return to the wielder when thrown.
Here is a quick write up of a Minor Mjolnir, it's probably not actually Thor's hammer but rather another mystic hammer crafted by the dwarfs and bestowed to Thor's Emissary by the God of Thunder. Or maybe it holds only a portion of the real Mjolnir's power in it due to the character's connection to Thor. Perhaps it is the real Mjolnir, and the character is only beginning to unlock it's true potential and claim their godhood as the New Thor.
-6 Item of Power (Minor Mjolnir)
(Weapon:3), Unbreakable, Returns to Wielder when Thrown
+2 Refresh (Big, Obvious, Can't be Easily Concealed)
-2 Inhuman Strength
-2 Inhuman Speed
+2 The Catch (Snake Venom)
-2 Inhuman Toughness
-2 Inhuman Recovery
-2 Breath Weapon (Lightning Bolt)
A mini Mjolnir could be made with only +1 Refresh at a cost of -7 Item of Power, and a Special Ability to shrink in size to a pendant when not in use.
With all the bonuses from Inhuman Strength it does (Weapon:5), and can shoot Lightning Bolts that do (Weapon:2) damage.
