How to Unlock the Underground Waypoint in Court of Fontaine

Head to the Fleuve Cendre Sewers

One of the waypoints is in the Court of Fontaine's Fleuve Cendre sewers. There are two entrances, both of which lead to the underground sewers.

Fleuve Cendre Sewers Entrance #1

The first entrance may be found west of Court of Fontaine, near the Cafe Lucerne. Enter the door and then descend the hole.

Turn right after reaching the bottom and pass through the little gap on the left side of the barrier. After getting through the metal barrier, you should see the waypoint right away.

Fleuve Cendre Sewers Entrance #2

The second entrance is east of Court of Fontaine, close to the Boucicaut general store. As with the first entrance, simply enter the door and glide down the hole until you reach the bottom.

Once you've reached the bottom, turn right until you reach the teleport waypoint.
