From my next project

My sophomore self-published effort is provisionally titled There is Therefore a Strange Land. Here's something from it:

Dice	Portal Type	Portal Opening	Special
1	Ordinary-looking door	Simply on opening the door	The portal leads to a limbo-like vestibule where a guardian checks equipment and confiscates roughly half the items (1-3 on a d6 for each item)
2	Out-of-place door (made of metal, leather, etc.)	At a certain time each day	The portal temporarily causes those passing through to forget how to speak (10-60 minutes)
3	Wardrobe	On “the magic words” being spoken	The portal temporarily blinds those passing through (10-30 minutes)
4	Chest	With a special key	The portal is twinned with another portal somewhere in the city; every time it opens, so does its twin – with a 1 in 6 possibility something from the bestiary, picked at random, slips through into the real world.
5	Sideboard cupboard	With a certain mixture of ingredients smeared on the forehead of those trying to enter	The portal closes for 1d6 days an hour after it is entered. It cannot be opened during that period.
6	Trapdoor	Knocking a certain code	The portal causes those entering to randomly switch hp totals, sexes, facial features, or similar. If only one person enters, swap two random stats.

And here's a piece of inspirational art:
