There's a guy named the Baru Sheppherd at the Limbo Desert in one of the buildings, and there's a quest you can do where he asks for 5 Ice Cubes and 5 Ice Gems. That's all the info I have right now... but yes, they're back, and Vult-r is still doing his thing!
And you know what, this is VERY good for EO's economy... now that Ice Cubes and Ice Gems have another use, and how Orons are an ingredient for another item, prices of everything will be going up because those items are needed more!
I recorded the whole thing and will be uploading it on my YouTube channel very soon... stay tuned.
