Discovered by the Initiative, this unique portal connects from a remote cave somewhere in Synthex to the Sanctuary in Commedia. All living beings that enter from the Synthex side shrink down to ¼ of their size, and the reverse occurs when they enter from the Commedia side.

Non-living objects don't change size, which creates some interesting challenges. So far this has been a stable, bi-directional portal.
