Eldritch Draught of the Einherjar

A small, hand-blown glass bottle with a thick, uneven texture, capped with a rough-cut green emerald-glass stopper. Inside, a viscous lime-green liquid glows with a faint, internal luminescence, filling exactly half the vessel. The bottle rests upon a weathered reindeer-hide pouch. Subtle, spindly runes for 'Stalwart' and 'Grave-Kin' are etched directly into the glass surface and the leather of the pouch, barely visible except when the green liquid passes behind them.
