Legends tell of the foolish King Grod Ketretus who reigned over the once wealthy Hiberian Province, that fell to poverty as the King funneled the province's resources into his own personal coffers. The king commissioned the elaborate Hiberian Labyrinth to protect these riches, guarded by the mighty minotaur Bjorras, hoping to cheat certain death and return one day to enjoy his riches.
Hiberia has since been relegated to the pages of myth and legend....until today.

How to Play

Visit the travelling scholar Vivyen in Windmoore to learn about her connection to King Grod Ketretus' story, and begin a quest to adventure to his labyrinth of lore. Travel through the energy portal to explore the labyrinth, tap into some of the King's riches, earn leaderboard points, and even take on the terrifying minotaur Bjorras himself. Beware of the King's tricky traps!

A Massive Maze
The Hiberian Labyrinth is a massive maze of twisting, turning hallways meant to confuse and distract you!
Here are a few tips to keep you from getting hopelessly lost:
Minimap
Use your minimap to navigate! Zoom out all the way (minimap zoom and opacity can be found in your Options menu).
Let the minimap show you where you've been and where you still need to venture.
Kill Counter
Before you can face Golden Bjorras you will need to kill all of the monsters in the Labyrinth. At the top of your screen you will see a message indicating "Kill All Enemies!"
When there are 50 (or fewer) enemies on screen this message changes to indicate the number of monsters left:
When all monsters are killed the message changes yet again to say "Kill Bjorras!"
Guide Arrows
When all enemies are defeated and Bjorras can be accessed you will see green 'guide' arrows on the floor at hallway intersections:
Follow these arrows to the final boss!
Camera
While in the Hiberian Labyrinth you can zoom, turn and pitch your camera angle!
Swipe the screen to adjust camera position. It's a great way to help you navigate.
Labyrinth Traps
All of King Ketretus' traps are engineered to inflict heavy damage.
Watch for the trap's warning indicators and stay away / out of the way before it activates.
Almost all of the Labyrinth traps will kill you if you are not careful!
The Spikes
Designed to cleave treasure-laden thieves in half!
Watch for the warning indicator on the dungeon floor. Don't be on top of these blades when they suddenly slice upwards!
Spikes are deadly any time they are visible. Don't cross while extended or you will take heavy damage!
The Ballista
Engineered to pierce gold-grabbing raiders with a fiery arrow!
A warning indicator appears on the ground beneath the ballista to indicate where it will fire its deadly projectile.
Projectiles can be avoided when they are in flight.
The Grinder
Built to cut thieves below the knees!

Grinder blades move back and forth along a fixed track. They have no warning indicator.
Keep your eyes peeled and you can side-step grinder blades to avoid damage.
The Grenade
Engineered to blast maze raiders to pieces!
Grenades indicate a line in which they will be fired. After they hit the ground, grenades explode and cause damage, knockback and stun!
Watch where the grenade lands and be sure to avoid the area.
The Flame
Designed to incinerate adventurers to ash!
A warning indicator will appear before the flames ignite.
Flames are deadly any time they are visible. Don't cross into the flames or you will take heavy damage!
The Ghost of King Ketretus
Condemned to roam the halls of his Labyrinth...
The dead King Ketretus is surrounded by a "terror aura" that will send you into a panic!
He cannot be damaged, killed, taunted, or otherwise affected by your skills... so keep your distance.
Avoid being caught in his wake - especially if you are near other deadly Labyrinth traps.
Quests
Completing the Hiberian Labyrinth dungeon for the first time and returning to Vivyen with the information she seeks will grant you the recipe for the Miserly Monarch's Gold Chest, allowing you to trade an Epic rarity set for a chest containing a bit (or a lot of!) the King's gold stash, up to 1,000,000g!

Return to Vivyen daily to complete another quest that grants a consumable recipe and components for the Massive Locked Hiberian Crate, which contains the chance to loot Level 81 Arcane Gear, Level 86 Legendary Weapons (Chakrams, Orbs, and Chainswords), Level 86 Legendary Elemental Gear, big time gold, and more.

Guaranteed Loot + Badge
The Massive Locked Hiberian Crate offers guaranteed loot and a new deluxe "Arcane Flames" Badge:

Boss Loot

On top of the glimmering prizes in event chests and crates, the minotaur boss Golden Bjorras is sitting on a hoard of his own, and has the chance to drop Level 16, 46, 26, 72, 76 and 81 Arcanes, as well as Level 81 Mythics and 86 Legendaries!
Plus, a new Hiberian Thief Vanity set, so you can raid the labyrinth in the most appropriate attire.
