Landmarks are a non-moving unit type that can serve a large number of functions.
Prime landmarks are marked by stacked stone cairns. They are locations that already have or are suitable for building defensive structures. Prime buildings are capable of defending themselves and act as central hubs for allied units. They can grant buffs to nearby units, allow Slayers to recruit Grunt units, and can be improved to create a stronger defensive position.
Each faction has a specific Stronghold that it must protect. If the stronghold is destroyed the player will lose the match.
Glyph Cairns are neutral landmarks that grant healing or buffs to units that are passing by. Glyph Cairns can be destroyed, but while taking damage they will alter their usually helpful auras into something much more dangerous.
