The doctor had traveled the lightless district before, and not just once. If one wanted to acquire alchemic ingredients, there simply was no alternative than to enter here. While no stranger to its oddities and horrors, possibly even somewhat known if one was to ask at the right places, it never ceased to cause a certain feeling of unease. Restlessness seemed to make the flexing of Caldwells right hand more frequent, until the doctor eventually adjusted their right glove. 

There wasn't much to steal from the doctor, but more importantly the kids mostly kept their distance to the masked figure. For the more superstitious folks, the outfit of a plague doctor wasn't exactly an omen of good health. Furthermore, half of the things one could acquire from the doctors pockets was potentially toxic, acidic or otherwise harmful to the fingers of your everyday thief.

Caldwell followed silently until they reached the run-down building of unapparent importance. The unspoken question about the past and present owners of the mansion spooked through their head as the doctor produced two flasks from the alchemical bag. The liquids within them were of a metallic grey and transparent respectively, though as soon as united and mixed, the result began shining in an almost phosphoric white. After adding a pinch of pitch black powder produced from one of the countless semi-obvious pouches in the plague doctor garments, the white shine turned into a murky orchid purple with black shapes twirling against the glass. The doctor corked up the round bottle, holding it in their right hand like some kind of abstract weapon, which it indeed was.

The little concoction Caldwell just mixed up was mostly resembling viscous gasoline in its features, with a little extra. Once in contact with oxygen and fabric, the liquid would eat into whatever surface, slightly damaging it but primarily sticking to it like tar. This process would then produce a gas with blinding properties, effectively disabling primary means of perception for the potential victim covered in it. Finally, it was highly flammable, causing the unlucky target to light up like a christmas tree if [i]anyone[/i] was to add fire to the equation.

Doctor Caldwell nodded towards Avrion, signalling him readyness.
