Si-Namuhu (pronounced SEE-nah-MOO-hoo), or memory liches, are a unique type of undead found primarily amongst the various cultures and peoples of the Wounds. Created through a series of occult rituals, Si-Namuhu are able to return themselves to existence, if not life, as long as they are remembered. Any damage to them, up to and including complete destruction, is merely a passing inconvenience as long as they are not forgotten.
Si-Namuhu are not necessarily evil, though many are, as some undergo the rituals for the purpose of continuing their peoples' stories and shared culture in the face of insurmountable odds. All, however, are fundamentally parasitic in nature, unable to exist without nestling into the consciousnesses of others, whether desired or not.
Prior to their transformation into undead, all prospective Si-Namuhu attempt to spread their legends as widely as possible, often intentionally crafting and sharing oral stories of their deeds to lands and peoples far away from their own, all in order to give them the best chance possible of survival. Yet they must take great care in shaping these narratives, for the memories themselves can reshape and alter the undead should they need to rely on them to return to the world.
Historically most Si-Namuhu have been Keleta-Ru gnomes or Fanakara humans, but they are not completely unknown amongst the dwarves of Harv Taruhm as well.
Some cultures have developed methods of countering the influence of unwanted Si-Namuhu. Within Fanakara tribes, it is not unusual to omit the names of those whose actions have passed into oral histories and make elaborate use of metaphors when recounting their tales, as by taking these precautions any potential Si-Namuhu are weakened and separated from their pasts.
