Tyrheim

Background
Tyrheim is a feudal death world whose people are tough, driven and deadly. The planet looks beautiful with rolling hills, amazing forests and stunning snow capped mountains but with a dark and bloody heart. The forests are filled with feral orks and deadly beasts and plants (with roughly 70-75% of all wild plants being toxic to all mammals save for transhumans and certain greenskinned savages). The mountains are filled with rogue tribes of chaos cultists who are rarely anything but a annoyance but the mountains also hold deadly beasts who are the true masters of the snowy peaks.

The Tempest Wolves helped the people established fortified cities using hive worlds as a basis but instead of packing everyone into cramped quarters they used the spire of the hive as the heart of the administration for the city while everyone else lived behind massive gun filled walls. For this the Chapter Master known as the Pack Master was named the king of the planet by the people cementing his role as planetary governor and defender of the sector.

Fortress-Monastery
The Wolf Den as it's known is build into one of the largest mountains in the northern hemisphere in the centre of the continent known as Vanar. It goes deep into the rock and dirt of the mountain with imposing metal doors at the end of the winding path designed to be a total kill-box against all attackers it's walls are covered in weapons and spikes to stop climbers who survive the hail of rockets, bolts, fire and lasers. Past the wall is a large courtyard which serves as the main outdoor training area for the marines and nephytes who call the fortress home. Looming over that courtyard is the main entrance to the Fortress-Monastery a towering door with various runes and carvings depicting the ancient gods of the world with the likeness of the emperor himself at the very top. The walls of the entrance has many slits for bolters and las-guns to poke out and rain all kinds of hell onto attackers with it's towers holding mortars.

Within the fortress past the gate and into the massive entrance hall with heroes of the planet's people as well as heroes and legends of the Chapter and Space Wolves are several side rooms with libraries, mess halls, indoor training rooms, small private temples and the several barracks needed to house the massive numbers of the chapter. Beyond these rooms past the entrance hall are the doors to The Forge, The Stables, The Armoury and the main temple to the emperor and the other major gods of the planet. Beyond this area past larger more secure doors is the Chapter MAster's throne room and the dorms of the Honour Guard and leadership of the Chapter itself.

The Forge is where the tech-marines work on the equipment of the chapter and upgrade it when needed, here The Master of the Forge works almost endlessly working on new ideas he might have. The Forge itself is always hot and smell of molten metal, fire and the sweat of his assistants, it is also filled with servitors to handle the liquid metal and other dangerous components.

The Stables are where the vehicles are stored and worked on by the tech-marines and their assistants. It is also where the Dreadnaught Armour is located and stored except The Chapter Master's armour who has it stored in his personal armoury, the stables itself isn't much different than other rooms used for the storage of vehicles used by other imperial factions.

The Armoury is the typical room you'd expect for a weapon storage. filled with rows and rows of weapons and explosives. This room also holds the entrance to the Relic Vault which itself is split into two rooms. The Armoury of Heroes where fallen brothers who fought with distinction and took down a powerful foe or large number of foes. The other room is The Armoury of the Damned where the weapons of worthy enemies are placed and sealed behind stasis fields and purity seals for the young future battle-brothers can view the accomplishments of those before them. The Armoury of Heroes is not as full as the main armoury or the Armoury of the Damned as it has proven quite hard for this new chapter's members to die.
