Sorry I don't know but I know where Sunburns soul gem is it is in Dragon's Peak about 5 minutes into it lean of the island and there is a dragon waiting there to take u to his soul gem
If you buy Pirate Seas, the soul gem is something with a cannon. I'm not sure where it is, but it is definitely in Pirate Seas. If you go by the cannon on land go right up the stairs and you will find the soul gem.
I'm pretty sure you find it in dragon's peak which you have to buy to unlock and it comes with sunburn.
