Gavin Rummery {Could start with explaining Hard Light here - the blog on Discord does a good job on that front:
Every weapon in Holdara is a bit like a Lightsaber - its core is made up of mechanical modular components that when combined emits "Hard Light" when it is activated that forms the weapon. This is because in Holdaran lore the only thing that can damage Nanovoid Shadow Wraiths is Hard Light, so the Holdarans must use Light to defeat the Darkness!

These are generally AOE effects that are offensive attacks, defensive shields, or buffs/support actions (e.g. energy transfer) to other Holdarans within the AOE area for the duration of the action.
