Background:

The plot card "Ascension - The Harbinger Approaches" says:

All four Temples must be in play to play this card. Place one Comet token on a Temple of your choice when this card is played and at the start of each week thereafter. All heroes have their maximum wounds and fatigue reduced by one for each Comet token on a Temple within three trails of their current location. In addition, if you ever end your turn with nine Comet tokens in play, you win the campaign. The heroes may enter your Keep while this card is in play.

It is possible to have heroes with only 8 wounds, while at the same time having 8 comets in play (assume all within 3 trails of heroes). This would reduce the hero in question to 0 wounds, which create a number of complications.
Does the hero die instantly, and if so how often and in what situation. What if the hero is reduced to zero wounds even while at Tamalir.

Questions:

Q1. What happens if the OL has 8 comets in play and a party with a hero with 8 wounds maximum moves into the influence area of all 8 comets?
A1. The hero is killed immediately and the OL earns CT according to the hero´s value. As long as the party is in the influence area of all 8 comets, that hero cannot take part in an encounter or dungeon or perform a Visit or Train/Recuperate action in a city or Secret Master in that influence area. He is effectively out of play and if that happens to affect the Final Battle, it is due to the party´s bad planning.
A2. The hero is killed immediately and the OL earns CT according to the hero´s value. As long as the party is in the influence area of all 8 comets, that hero cannot take part in an encounter or dungeon but hangs back in Tamalir and may Visit or Train/Recuperate there, if Tamalir is not in that influence area.
A3. The hero is killed immediately as soon as the the dungeon level or encounter is set-up. In encounters he stays out as usual, in a Dungeon level he is moved to Tamalir´s temple and may restock every turn for the duration of the dungeon. If Tamalir is in the influence area, he remains out of play.
A4. The hero´s maximum wounds are reduced to one as long as the party is in the influence area of all 8 comets. Easy prey, but he still can participate.
A5. Something else?

Q2. If Tamalir is in the influence area: What happens if the party returns after a dungeon, or if the hero restocks, or if the hero is killed in a dungeon outside of the influence area?
A 1. ummm... easy if the answer above was A4, otherwise will be based on the answer above.

Some of the OL keeps require the combined action of 4 heroes in order to access the final battle. If a hero can't participate in the Spider Queen's lair or in the Great Wyrm's lair, then the final battle cannot be started and the game never ends.

This could happen even if the hero's maximum wounds are reduced to 1, because the OL will be killing that hero constantly before he can reach the spot he must ocupy. His comarades won't be able to protect him because they need to be on other spots (this is more evident on the Spider Queen's lair). So the heroes cannot progress but they don't inmediately lose.

To put an end to this, the rule of the cicling OL deck could be changed. If the OL's deck is shuffeled twice while in the OL's lair 5th level (the OL keep) then the heroes automatically lose the game as if they had been killed by the avatar.
