Final Rewards in Magatia

So, can I toss both capes after all is said and done?
Or will they not speak to me on the off chance they add more quests?
I really don't want to have 2 more items taking up space in my inventory.
(I think I'm going to choose the last option, the capes don't really seem worth upgrading.)

98% sure theres lost cape quests, drop em when you finish, you can get em again later if need be.
