Rules of the Holy Grail War

1. The Holy Grail War will occur every 50 years. Selection of the participants will occur a year before initiation.
2. No more than 5 factions will be selected to participate. Selection is randomly done by the Grail itself.
3. Each faction shall form a team of warriors to fight other factions' warrior teams. Participants must go through an analysis ritual to see if the Grail shall allow them to join as a warrior.
4. Non-participants are not allowed to interfere with any battles between Grail War participants, lest they be cursed by the Grail. Participants in-turn may not form alliances with non-participants and use them against other participants. Interference is judged under the scrutiny of the Holy Grail.
5. Each faction will be summoned 2 official "faction servants" to aid in their battles. Should a faction's 2 servants be defeated, the opposing party may offer an ultimatum of either a contract of sorts to continue fighting or have the faction lose the Grail War. The contract's validity is determined by the Grail.
6. Some participants may be granted a servant should their internal magical energies be capable enough to allow the Grail to grant them one. Servants are automatically counted as a particpant.
7. During the war, each faction will be required to complete certain tasks and challenges issued by the Grail. Once designated tasks have been completed, said faction warrior teams may issue and prepare to challenge another faction and their servants directly. If a faction willingly attacks another faction or its warriors before completing said tasks, they shall be disqualified. If a warrior acts upon this, the individual will be disqualified and cursed.
8. The War will go on for no more than 1 year. If a year passes and no faction is victorious, all participants will be apparated into an outer plane of existence for one final deathmatch against every single remaining participating faction.
9. The winning faction will receive the grail within 12 hours. The Grail will appear at a designated area that all remaining participants will be notified of.
10. The Grail will be able to grant one major wish to the faction leader as well as a few lesser wishes for the remaining Grail Warriors. Constitution of "lesser" is done under the scrutiny of the Grail.
11. The wish cannot be used to destroy the Grail in any way, as destruction of the Grail will lead to the destruction of the world.
