Useful info about the sandencre

The sandencre is a substance common to every inhumans in the Lair, it was transmitted by the four ancestral beings (the Lord of the Underrealm's children). It is a thick black liquid, every one in the Lair has a least one drop of it in their organism. Some even like having it as tattooes. The sandencre can be used as a weapon but it requires training and control: it can be materialized in the form of a thick black smoke through the ends of the body and be shaped in any form one likes, some stronger inhumans can materialize it from their back or chest.

The only way the sandencre can be transmitted is through cuts. Once the subject's flesh is cut open, the sandencre must be poured into it, it will most likely penetrates the body by itself and will end up flowing along with the bloodflow. The sandencre is harmful to humans, not to inhumans but if one inhuman harms another with the sandencre, pain will be felt but no physical wound will be caused.
