Assassin looked at the portal and sighed. He knew what this meant. He had some experience with life, magic portals to ancient places, and all kinds of such things. He knew that he was going to be awhile, especially if he was learning some new, ancient technique -- one that wasn't magic.
He held out his right arm and muttered, "Vizoke, simaba."
The cloak sleeve of his right arm suddenly turned to black energy which quickly dispersed to reveal his arm was made of the same 'skin' clay-like covering as the rest of his body. The white material suddenly moved of its own accord, ripping itself from the shoulder of Assassin.. But there was no blood. In the place of his arm, there suddenly was weaved a new arm -- a normal arm with normal skin.
The protective-covering arm suddenly grew in shape and size. Suddenly, there he was.. A man in black clothing.
"Sirius.. Welcome."
"Thank you," the man, Sirius, replied.
"You know your job."
"Yes, sir."
"Disperse."
And suddenly, the form of Sirius turned to black energy and dispersed, a form of teleportation. Assassin walked through the door.
