i absorbed lord rhomulous into me during a trip to his dimension that i discovered accidently. he can be combined with my main weapon to greatly increase it's strenght or he can take over my body which gives him acces to a slightly alered set of powers than my own.
for instance in necron he turns into a werewolf instead of a zombie and in terron he gets plant manipulation and animal fusion.
we can be split apart for a short while but our powers will be slightly decreased and we gradually weaken over time
