Coalescence is the process by which soulbleed congeals to form undead beings in the Underworld. This process has formed most denizens of the plane naturally, from the mighty King Ugrach to the lowly skeletal warrior, but it is known that Ugrach has since then discovered how to use the Soulbleed Nexus as a means of forcing coalescence, thus moulding soulbleed into his own undead creations. The exact means by which he achieves this are sought by the Magister Dominar.
