I'm staying at level one on my current character to spite the game. I got sick of NPCs getting killed due to the level scaling system. Well, all is going fine, but an unmarked quest at the College of Winterhold asked me to get seven empty greater soul gems. Merchants only seem to sell petty soul gems because of my level - they do sell filled greater soul gems, though. Does anyone know where I can find some empty greater soul gems despite being level one?

I know I can reject the quest, but I'd rather not do that. It's not my style.
