So you're going to warp into the DC world carrying a 20 foot tall crystal, held up by giant adamantine braces, that shoot 30 feet long dark energy tentacles in every direction, and is hooked up to an undead god-fetus?
I mean I'm pretty sure that's going to be "noticeable" no matter what magic items you have to slap on it after you beam in. And the OP doesn't say anything about getting yourself a secret fortress to have all this set up in or anything.
