Francium asteride

Francium asteride (FrAe) is a compound formed from the chemical reaction between francium and asterine. The compound is known for its extreme rarity and its usage in anti-Aster weaponry.

The compound is virtually nonexistent in the prime timeline as both of the elements, especially asterine, rarely exist in significant quantities. However, large pockets of francium and asterine exist in the Alvire timeline, allowing for the compound to form.
