Six days of growth and preparation, then off to the human borderlands

For the next two days you gorge yourself, processing as fast as you can, making the most of your time. Your human body is strengthened, your fibers reinforce muscle and tendon, skin and bone. All manner of tentacles hide themselves in Lothar's body, his organs are rearranged, his entire body carefully reconstructed to suit your needs. He is your weapon.

The following four days allow your new body to heal from all of your internal manipulations, with your assistance. You are a surgeon, working flawlessly and expertly from the inside, able to suture or reinforce any body part at will, able to direct his systems without their usual overcompensating hiccups and self-defeating processes. Under your care, healing that should take months takes place in hours and days. Your body isn't fully healed in those few days of recovery, but it functions well considering the changes you had made, and your filiments and sutures compensate for any healing your new body still worked on.

Finally you suit up. You have to sort through the gear of captured prisoners, as the orcish and goblin weaponry and armor would both not properly fit and their stylings would bring up questions. From Lothar's mind you are even able to recognize some of his old gear, not yet broken down and repurposed for the Dark Lord's army.

Armed, armored, geared, fed, and enhanced, you let the Dark Lord know that you were ready, and supplied with provisions you journey into the borderlands; making your way West towards the kingdom of Man.
