What Lancasters do best

A variety of artificially-created crystals are used for many purposes in the Spire. Each type of crystal channels energy in a different way, ranging from light to propulsion, from electricity to weapons.

They also range in rarity. Lumin crystals are so common that their eventual loss means very little, but a core crystal is so expensive and rare that non-Fleet ships can only afford second or third-hand ones.

This is partially a reflection of how long it takes to create them. While lumin crystals are tiny and simple, a core crystal requires decades or even centuries to grow. Furthermore, they are only grown in the vattery of a single family, House Lancaster
