A future version of my character, "Farseeker"
Xukhezur Kavinath, could be a good fit for this RP.... save that his technology as currently presented is quite advanced.
What's not listed in his description for his future version, is the all the technological equipment he keeps stored in his protomorphic demiplane.
He can use his magic infusions to conjure functional replicas (composed of protomatter) of any object that remains in one of his protomorphic demiplanes (no more than one replica for each object)... that persist until they leave his possession for more than six seconds, or the original objects on which they are based leave his demiplane... at which point such a replica will decay harmlessly into nothing.
