Lesser monsters: the things that lurk.

Not every monster is a legend. Lesser evils lurk in the sea, the sand and the sky. Some come only to their lairs, and each has a sign showing where it lives.

Rust lampreys

They gather under a rusted buoy and wait for a hull. They fasten onto a boat and chew through its metal. Watch the hull of anything you sail.

Bobbit snares

A bobbit snare waits in the sand below a bone-banded buoy. It is set to catch whoever walks past.

Hull leeches

They drill into a starship's hull and cling there. They are the lesser threat of the stars, and they will drill through your ship if you leave them.

Echo eels

They sing in the water under a copper-banded buoy. They copy your friends' calls to lure you in, and then strike.

Glassheads

They stare up from the deep below a glass-banded buoy, watching the surface for a swimmer.

Firehawks

Birds that carry burning sticks to set forests and bases alight, like the real Australian raptors. A burnt nest, with a dead trunk and a scorched top, is where one roosts. It comes again.

Ballwisps

Glowing balls of lightning that drift through walls in storms. They gather round a wizard's staff with a glowing orb, in a ring of scorched earth, whenever it rains. They last about a minute each, and they hurt on contact.

Flingers

They grab you on the light moons and throw you high into the sky. A cairn of cracked boulders marks where one lairs, and it comes every time.

Bower thieves

Glossy birds that pick one kind of block from your build and steal every one of them, flying each home to pile at their bower. A bower of sticks, glass and copper marks their lair.

Lookalikes

Weeds that look exactly like your crops, and bite at harvest time. Check a field before you harvest it.

The Quiet Lake

Now and then it breathes out an invisible gas that rolls downhill. Your torches going out is the only warning. Move up out of low ground.

Compass worms

They make your compass and your map lie.

Dust traders

Their fine goods crumble to dust once you leave their world.

The Bloop

A groan from three kilometres away out at sea, so low you feel it. Every fish flees. Nobody has yet seen what makes it.

Barnacles

They crown a boat left lying at sea, until she crawls and turns to reef.

The Sealed Ones

Creatures that have never seen daylight, in a cave sealed for millions of years. They wake only when you break in.

Lairs and signs

Most lesser evils lair in one place, and their sign is put up nearby. Read how lairs work on Lairs and how legends come back.
