You have certainly had your work cut out for you with Lioneye's Legion. Do not concern yourself with Marceus' complaints. Our Emperor is fully aware of the General's fickle nature.
As to your need to accelerate the implantation process, I can recommend a quite simple alteration. Dip the gem in a boiling solution of six parts blood and one part thaumetic sulphite for no more than thirteen seconds. Any longer and you invite the crystal's wrath.
Once the gem is withdrawn from the solution, you have but a few seconds to install the gem in the prepared flesh and close the wound. Should the gem cool too much prior to implantation, it will become inert and your patient with it.
Trust in that bountiful talent of yours, Shavronne. My thoughts are with you.
