Defender of the Haven
Many Tremere have relied upon Gargoyles to defend their havens while they work other rituals to plot and scheme against the Tzimisce. So, while they are engrossed in their research, they need their Gargoyle guardians to be extra alert, and thus this ritual was devised. With it, the Gargoyle becomes linked with the haven (up to the size of a small castle) and may detect intruders of any sort, even if they are out of sight or under the veil of Obfuscate.
System: This ritual can only be used on Gargoyles of 10th generation or lower. The ritual takes an entire night to complete and involves taking the Gargoyle to the various cardinal boundaries of the haven, where a pint of the Gargoyle's vitae is infused into the structure. The Tremere also expends a point of Willpower to activate the ritual. When completed, the Gargoyle may detect anyone within the structure on a Perception + Alertness roll (difficulty 6). If the intruder is attempting to hide, he makes an opposed roll Self-Control + Stealth roll (sic) (or other appropriate roll), also against difficulty 6. This ritual must be cast during the full moon and works for the Gargoyle only in the structure in which the ritual was cast.
