This tactical dagger was forged from the hull of the SS Veles 🚢, a bioresearch vessel that was lost in the 2268 "Red Tide" incident—a catastrophic algal bloom that poisoned 70% of the Atlantic Ocean’s surface. The hull’s titanium alloy had absorbed high concentrations of a genetically modified algae, Porphyra Mortis, which secretes a neurotoxin that causes violent hallucinations. The blade’s single central groove is not for drainage, but to channel this residual toxin, which coats the edge with each strike. The loop-shaped handle is designed for reverse-grip combat, allowing the wielder to deliver devastating upward slashes that target the throat or armpit.

However, the weapon carries the curse of the Veles. The ship’s crew, who were driven mad by the algae, sealed their final log entries in the hull’s alloy before the vessel sank. Those who wield the dagger report hearing the crew’s screams and delirious whispers in their heads, urging them to "join the tide." Worse, the algae in the alloy is still active; prolonged contact with the blade causes the user’s skin to develop a purple, scale-like rash that spreads to the entire body, eventually leading to organ failure. In 2271, a mercenary who stole the dagger was found dead in a fishing trawler, his body covered in the rash, with the words "THE TIDE COMES" scrawled on the wall in his own blood.

The dagger was recovered by the Oceanic Preservation Front 🌊, an eco-terrorist group that believes the Red Tide was a "natural correction" by the planet. They use the dagger in attacks on corporate fishing vessels, hoping to spread the algae and "purge" humanity from the oceans. Today, it is known as the "Red Tide Fang," a weapon that poisons both its victims and its wielder.
