Mini-Dungeon: “The Grounding Failure”

Core Concept

This site was an early Ormath-era attempt to regulate ley pressure before antigravity isolation was perfected. The obelisks were partially grounded. When pressure surged, feedback cascaded downward instead of up.

What remains above ground is misleading.
The real damage is below.

The Crossroads Ruin

Lair of the Tundra Dragon

Threat Structure:
Surface hunters → subterranean brutes → aerial apex predator

This ruin is dangerous before the dragon ever appears.

Surface Tier: Giant Arctic Wolf Spiders

Primary Patrol Threat

Number Appearing:

• 4–6 spiders total

• Encountered in groups of 1–3

Why They Are Here

The broken stone platforms, collapsed plinths, and half-buried chains create perfect hunting ground. The spiders are not servants. They are tolerated.

The tundra dragon:

• ignores them entirely,

• occasionally eats one if hungry,

• benefits from the way they thin travelers.

Patrol Pattern

• Spiders patrol just below the surface, emerging from shallow burrows or cracks.

• They favor:

  • the collapsed forecourt,

  • chain piles,

  • shaded stone near cliff edges.

Tactics

• Ambush from below or behind broken stone

• Attempt to poison and withdraw

• Drag paralyzed prey toward burrows or deeper shafts

They do not pursue into the deep ruin.

Play Impact

• Establishes danger immediately

• Forces slow movement and caution

• Burns resources before deeper threats

Mid-Level: Ice Trolls

Territorial Brutes

Number Appearing:

• 1–2 Ice Trolls

• Never encountered together unless alarmed

Why They Are Here

The lower ruin retains:

• residual warmth in stone,

• carcasses dragged down by spiders,

• protection from wind and aerial predators.

The trolls have learned:

• the dragon does not tolerate noise near its lair,

• but ignores activity deeper down.

Placement

• One troll lairs near:

  • the chain anchor gallery, or

  • a choke point below the shaft.

• The second (if used) occupies a separate chamber, never adjacent.

Behavior

• Aggressive and territorial

• Uses terrain, rubble, and vertical cover

• Retreats deeper if badly wounded

Relationship to the Dragon

The dragon tolerates them because:

• they keep the lower chambers clear,

• they do not challenge the surface,

• they leave the best remains untouched.

If a troll wanders too high, it dies.

Bottom Tier: The Tundra Dragon

Apex Predator

Number Appearing:

• 1 (adult; as statted)

Lair Placement

The dragon’s true lair lies:

• beneath the lowest intact chamber,

• partially open to the sky via collapsed vents,

• with burrow exits leading outward and downward.

It can:

• enter or exit vertically,

• burrow if pressed,

• attack from above or below.

Dragon Behavior in This Lair

The dragon:

• hunts from the air,

• returns prey here to feed,

• sleeps on stone warmed by ancient infrastructure.

It does not fight to the death unless cornered.

Encounter Timing

• If surface fighting is loud or prolonged, the dragon becomes aware.

• If trolls are killed noisily, it investigates later.

• If PCs retreat, the dragon remembers.

Lair Ecology Summary

This structure:

• rewards careful play,

• punishes rushing,

• and allows partial victories.

Treasure Logic

• Spiders: no hoard, only grisly remains

• Trolls: scattered gear, half-eaten bodies, minor loot

• Dragon: full hoard (TT H), frozen into stone and ice

The best treasure is deep, and earning it means surviving everything else.
