God's statue

Basics
At various places around Kryta and Ascalon you can find statues of the 5 Gods of Tyria:
 * Balthazar - God of War and Fire
 * Dwayna - Goddess of Life and Air
 * Grenth - God of Death and Ice
 * Melandru - Goddess of Nature and Earth
 * Lyssa - Goddess of Beauty and Illusion

Some of the statues are whole, some are broken (especially in ruined post-searing Ascalon).

Note: Also in some rare places you can find beautiful murals of the 5 gods, although these are eyecandy only, and have no function.

Statue "Status" (active/inactive)
The statues change their appearance depending on whether your territory has the Favor of the Gods. If yes, then the statues become "active":
 * All broken statues become whole.
 * Balthazar: Statue will be burning with flames.
 * Dwayna: Statue will have water running between its pieces.
 * Grenth: Statue will have white mist flowing from it.
 * Melandru: Statue will have water flowing through it.
 * Lyssa: Statue will have a golden light (with glittering sparks falling) at the base and her figure will be lit with a white light. Without the favor, the statue will be dim and there will be thorns engulfing her figure.

Gods' Avatars
If a statue is "active" (this means if your territory has the Favor of the Gods) you can summon the god's avatar at his statue - whether it's broken or whole. You do this by walking up to the inscription at the statue base and typing "/kneel" in console.

All avatars offer your party special bonuses if you make an offering (pay some gold):
 * Offering to Conquest(50 gold): Dwayna's Blessing - a health regeneration enchantment similar to Mending
 * Offering to Courage(100 gold): Morale Boost +2% or reduction of Death Penalty (if you have any)

Furthermore some avatars offer special quests and/or access to the Realms of the Gods.
