The keys I’m interested in are:
Never Alone Arctic Collection
The Silent Age
12 is Better Than 6
The Flame in the Flood
Planetary Annihilation: Titans
But if it’s first come, first serve, then I’ll take Eon Altar since Will already claimed Planetary Annihilation.
About the gleam, maybe the ability to create a mass craft of colored gleam using only one piece of raw colored gleam could be a crafting skill.
