Summon felines. Yes, this is a grand plan. With your harem of cats, it should be easy to turn it into an org- yeah, let's not get into that. You don't want to be coated in awkward liquids.
Still, you attempt to conjure something out of nothing... and...
Nothing happens. At least, nothing visible happens. Oh well, the cats are disposable anyway. Instead, you turn to Hyenas, and you attempt to do the impossible again. With what? Nothing? Most things require reagents. Maybe if you turned all the dead thieves into skin-hounds, you'd have a sizeable army of combat slaves to do your bidding.
As for the handful of cats you have gathered around you, you decided that, since you couldn't summon either cats or hyena-dogs out of nothing, you'd rather have them sing praises to your contours. So you did. The room's a mess of mewls and raving tentacles from mind-flayers.
Wait. Mind-flayers? Oh dear, did you just successfully summon Hastur? Just in case, you try to make your flesh-thralls say "Pazuzu, Pazuzu, Pazuzu" three times, to summon the dark, winged lord, hopefully as a bargaining chip to use against Hastur if in case he wants to kill your followers and use you for himself.
...
...to no avail. The thralls barge in, lacking heads and having in place a fleshy, tentacular growth in its stead. Whoops, looks like Hastur really wants your hide, if you had a leathery hide instead of a fine porcelain exterior.
--------
In the distance, the felines seem affixed to one direction, and they move in a raving, possessed behavior towards the source of their compulsion... daring to cross waters they could not even survive swimming into...
--------
You are a vase, fixed, but lacking thralls and only having a harem of mewling feline slaves as your bargaining chip at the moment. Hastur seems interested in you. What do you do?
