Hideaways are the most basic of all combat based cosmic anomalies, easily completed with even a tech 1 fitted combat frigate. They come in two varieties, one with a bunker an another with a radar tower.
This will continue until the site is completed and while most sites end without event there are two rare events that can happen when a Hideaway is completed. The first we will cover is a faction commander npc spawning at the site. A message may appear in local and the final wave will include a npc with a prefix related to their faction before it's name. These prefixes are Sentient, Dark Blood, Shadow Serpentis, Domination, Dread Guristas, and True Sansha . Below is what a Domination spawn looks like.
