So this could be a spoiler, but probably not. A while back two triangular glowing crystals stored within wooden cases were teased, and many people couldn't figure out what they were for. It has recently been discovered that there are at least two altars found in uncharted areas (I won't disclose here) that have triangular slots for inserting these crystals.
Has anyone been able to find one of these crystals? If so, have you found the altars as well?
