Using "re_emergent" to make factions undieable

[Lysandros]

I'm using the BI.EXE with EB 1.1 and have managed to add the horde ability to all factions after reading the excellent guide at http://www.twcenter.net/wiki/Hording...tions_-_RTW/BI Everything works fine so far. But what I didn't get is: is it enough to add "re_emergent" to a faction to make it reappear or do I also have to add "spawned_by" or "spawns_on_revolt" or another command?
