The keel are a species from the underside of Ankar, unaccustomed to the sunlight and environment on the top side. They’ve come to subjugate the top-dwellers and end the Source war that has threatened the entire island, including those who live below.
Unable to deal with the surface elements, the keel have developed new technology that protects them from the light of day. This void creation tech allows them to cover large swaths of the island in artificial darkness, allowing the keel to operate at full strength and leaving their enemies cowering in fear.
Keel minions are Promoted through their spires. While a keel Minion is on a Hex Group that has one or more keel spires on it, it is Promoted. However, if a Promoted Minion is no longer occupying a Hex Group with a keel Spire, it demotes back to its Basic Side. When keel minions demote, they lose all Health in excess of their new max, but do not lose any upgrade chips they have.
Minion promotion and demotion interrupts any other effect, with the exception of Movement. When moving, keel minions finish their full Movement and then assess whether to promote or demote.
Spires
The keel start with access to all four of their Spire types.
