Black Circle Treasure Map Quest

this involves getting the 'folded schematics' from the hooded thief, giving them to jerome and this happens:

Jerome, Paradise's master thief says 'Well it's a map of Midgaard...
marked with entrances to Paradise. Well that explains why I've been
seeing so many new faces recently.'

Jerome, Paradise's master thief says 'I so wish they wouldn't circulate
maps like this for everyone to see, but there it is....'

Squinting his eyes, Jerome examines the map of Paradise in more detail.

Jerome, Paradise's master thief says 'This marking, to the West of the
city... this is where we started finding the old bones. It's possible
this is what the scaled ones are after.'

Jerome, Paradise's master thief says 'Come to think of it, our dig site
is the only significant marking I see; why it's practically a treasure
map! You don't think someone drew this just to lead---'

Someone concentrates deeply...

Some folded schematics float into someone's hands.

Someone leaves west.

Jerome, Paradise's master thief exclaims 'What the... did you just see
what I---? BLAST IT!'

Jerome, Paradise's master thief exclaims 'If that's what the Black
Circle was after, we can't let them escape. Stop standing around! After
them!'

then there are three Black Circle Assassins to find and kill, whence they drop three different tattoo items. get all three and then give one of them to jerome and he will give you a reward. they are: 'tattoo of a black shining sun', 'a black scale tattoo', and 'tattoed pair of black wings'.

the Assassins use psi spells and are fairly difficult to solo for smaller heroes. also there seems to be a timer, so they will disappear after a little while, for example if you kill one and go back to sanc to regen. however, you can acquire the tattoos at different times, you'll just need to give jerome the schematics again to get the Assassins to repop.
