Hospitality is one of the three great virtues of the ancient Celts, and a similarly honorable virtue to the modern Fianna. Ordinarily, hospitality is a given at a hearth, but occasionally it needs to be formally stated in a binding fashion; perhaps the seeker is a rival, or has bad blood with others at the sept and needs protection. In such circumstances, the rite is performed. The grantor (typically the righ or the owner of the hall or territory) is required to give his guest food, shelter and reasonable comforts for three days, as well as protection from foes (without or within). In return, the supplicant is expected to be the model guest, neither stealing, starting fights nor otherwise bringing trouble to the household. And be sure that even if the offense isn't obvious, the spirits that witnessed the oath will find a way to bring it to everyone's attention.
Typically, only the grantor needs to know the ritual. The supplicant formally asks for hospitality, usually reciting lineage and titles in the formal way. The host replies in formal language, granting her protection and a place in her hall. If the rite fails, the delivery seems forced and all present will feel the awkwardness of the moment. If successful, both parties are bound to their bargain. Should either one break the bargain, that party loses Honor Renown (-4 for the host, -2 for guest). Ordinarily, no Renown is gained if both live up to their ends of the bargain, but if there is an element of danger (guest and host are bitter rivals or even enemies, for instance) the righ and guest gain two and one temporary Honor respectively. If the righ is notably miserly, she gains but one point; if outstandingly generous, or required to go to great lengths to defend the guest (sustaining grievous injury, destruction of the hall, loss of honor, or something equally costly), she may gain three. The Storyteller should be careful that this doesn't become a font of 'free Renown'; Honor should be awarded only if there's something at stake - for instance, being a polite host to a guest that's insulted you or is a rival, or being a model guest despite constant provocation. After three days (usually measured to sunset, but typically stated during the rite), all bets are off; if the guest is in trouble, he'd better make tracks.
