Primary
Follow the path in order to chase the Shining Blade Scouts and rescue the Chosen. Some places along the path are occupied by Entangling Roots, which will block the way. Kill the Entangling Roots to remove the plant wall blocking the way. After the first cut-scene, a large number of centaurs will come at you, so try to deal with one mob at a time (marked A on the map). After the second cut-scene, kill the spiders to save the Chosen and complete the mission.

Note: standing in the Maguuma jungle waters gives you the Fount Of Maguuma environmental effect.

Note: You will be accompanied by two White Mantle Knights at the beginning of the mission, but as they do not show up in the Party window as Allies and tend to run ahead they will usually be killed quickly. Even if they do survive the first part of the mission, they will not advance beyond the first cutscene area anyways.

Bug! After killing the first Entangling Roots, the "wall" of vines may not retract, preventing you from continuing with the mission. If this happens, you must restart the mission.
Bug! Sometimes, the Shining Blade Scouts will get stuck on the Centaurs or their Spirits of Symbiosis, allowing the players to kill them.
Bug! It is possible for Evennia to die during the final battle with the spiders. If this happens, you can still complete the mission, but her body will not be present in the following cutscene. She says her lines anyway.

Bonus
Early on in this mission you will reach an easily-missed crossroads. In addition to the path you came from and the path that goes forward (mission path), there are paths to the left and right. Go left and watch out for a path leading off from it, to the left. At the end of that path you will see two Centaur Scouts (marked 1 on the map). This is the most critical part of the bonus - Do not attack them. The centaurs will begin talking about two centaur clan leaders meeting to discuss banding against the humans. Wait until their conversation is over, or you will not be able to complete the bonus. After they have finished talking, a bonus objective will appear, telling you to defeat them. Now it is safe to attack. They will drop a Vine Seed. Take it with you and continue with your quest.

With the vine seed, return to the crossroads and continue down the mission path. You can freely drop the vine seed and pick it back up later.

Further on in the mission, you will get to a cut-scene where you see the person you're chasing running and a large number of centaurs rushing toward you. Kill them, and then head up the path the centaurs ran down (northward and eastward). You will find a glowing circle where you can plant your vine seed to create a Vine Bridge (marked 2 on the map). Then you will be faced with quite a number of centaurs and four centaur bosses, including the two centaur bosses mentioned by the conversing scouts, whose deaths will complete the bonus objective (marked 3 on the map).

Be very careful not to aggro more than one group of centaurs at a time. There are six patrol groups (in addition to two stationary groups) before the vine bridge and it is easy to be blindsided. Don't be in a hurry to advance into the path of additional roaming groups. There is one group in the far north that starts patrolling only after it comes onto a player's radar, but has a route that takes it much further south than another group that starts patrolling sooner. It is easier if you take the right fork at point A rather than the path shown on the current map.

Note: If you aggro the two centaurs upon entering, you can still run back. After giving up the chase, they will return to their initial position to play the dialogue.

Bug! If, while attempting the bonus, you drop the vine seed in the same place that the Shining Blade Scouts do during the cutscene, it will disappear and you will be unable to continue with the bonus.
