| Land and Mountains: |
| • The Lost Country: |
Wide Northern lands (their former home), that Desoto and Avias had to travel through to reach the Canyon (humans' place). Large woods. A dried-out riverbed leads down into the Canyon. |
| • Bear Forest: |
A rich, dark forest at the North of Eru Canyon, inhabited by bears (a dangerous place for wolves). |
• Eru Canyon: |
The large Canyon, about 75km diameter, surrounded by high precipices in the West and South. Crossed by the river Sirion. Three lakes: Desert Lake, Stone Lake and Lanthir Lake. Various landscapes and interesting geographie. Hunting ground of the WeuUkoo Wolves. |
• The Mountainous Ridge: |
Impregnable high mountain chain in the South-West, dividing the Sarn Forest and the Sidh Forest. |
| |
| Forests: |
| • Sarn Eryn: |
"The Stone Forest", on top of the high Western precipices. Crossed by the mountain river, which ends in the Lanthir Falls. The only way to cross that river is a small bridge near the waterfalls. Former home of Sombra and her family. |
| • Sidh Eryn: |
"The Forest of Peace", covering the Southern and highest precipices. Home of the WeuUkoo Wolves. Bordering on the huge and impregnable Mountainous Ridge in the West, and only accessible through a tiny pass on the high precipices ("Fennas"), which makes it a very safe place. |
| |
| Water: |
| • Lanthir Falls: |
Very high water falls, bringing the mountain river down the canyon in form of the River Sirion. |
| • River Sirion: |
Wide and wild river crossing the Eru Canyon, connected to the Stone Lake. Has one restriction in the middle where you can cross the river. In the North it is bridged by the Northern Pass. |
| • The water hole: |
The WeuUkoo Wolves' main place for drinking, but they also go down the Fennas from time to time to visit and drink from the nearby branch of the River Sirion. |
| • The Lakes: |
The three lakes within Eru Canyon - the Desert Lake (biggest one), the Stone Lake and the Lanthir Lake (smallest one). |
| |
| Ways and passes: |
| • Fennas (The Pass): |
The only access to the Sidh Forest, like a gate. The small way up the precipices is very cliffy and difficult to climb. |
| • The Look-Out: |
A ledge about 60m above the canyon ground. It is only accessible through a secret submontane passage beginning in one of the Sentry hills/caves at the Fennas Pass. |
| • The secret path: |
A tiny path on the Southern side of the Lanthir Falls, the only way down from Sarn Eryn to the canyon. |
| |
| Housing: |
| • The Main Den: |
Main den of the pack, consisting of 2 large dens with several levels inside, forming an open circle. |
| • The Sentry Hills: |
The hills on each side of the Fennas Pass, perfect place to guard the only access to that area. The left hill includes a den, which leads to the Look-Out Ledge through a secret submontane passage. |
