Gwynevere is a character in Dark Souls. She is the Princess of Sunlight and daughter of Lord Gwyn. She gives the Lordvessel to the player and allows them to join the Princess' Guard Covenant. The Gwynevere you see in game is an illusion created by Gwyndolin in order to manipulate the player.
Gwynevere only drops the Lordvessel if it was not already given to the player.
Dark Anor Londo
If the player attacks Gwynevere, Anor Londo will darken as the illusion created by her younger brother fades. All the enemies, except the painting guardians and the Silver Knights, as well as any illusions will disappear. However, The NPCs (the Fire Keeper and the Giant Blacksmith) will remain there.
Although Gwynevere herself exists, she left Anor Londo long before the Chosen Undead came to Lordran along with other deities.
Effect of Dark Anor Londo
- After Anor Londo darkens, you will be constantly invaded by members of the Darkmoon Covenant, as long as you're in human form and online. Like every areas, killing available bosses (Gwyndolin) will stop invasions.
- Also the Firekeeper of the first bonfire in Anor Londo becomes hostile, and will move near to the rotating tower as well as two knights, a Balder Knight among with a Berenike Knight, will appear in the great corridor where the two giants were, right before Ornstein and Smough fogwall.
- Finally, if the player dies in Dark Anor Londo, they will always respawn at the first bonfire, even if it's unlit. Using a homeward bone will not warp to another bonfire. This is why the player should not kill the firekeeper as long as Gwyndolin is alive, because he will be able to warp from this bonfire.
- Killing Gwynevere will be considered as a permanent sin in PvE.
- Amazing chest ahead
- The Balder and Berenike Knights used to respawn and could be farmed for souls. After patch 1.06 they will no longer respawn after being killed.
- It is possible to steal at least 3 humanity from these using Dark Hand.
