How does someone collect a Geas from a Lilim? How does a Lilim collect her own Geases from those who owe her?
The holder of the Geas must track down the person to redeem it. Either a Geas-hook (a potential Geas) or a Geas itself is a connection between the Lilim and the victim, so you can use the Celestial Song of Affinity (Liber Reliquarum, p. 29 and the Liber Canticorum). The GM may also allow a Geas to be called in via telephone or the Celestial Song of Tongues.
