The leader of a handful of Kohl survivors trapped for years in an artificial dream world, where a being born of their own fear holds them hostage.
Viorsa is the planner who led his people's attempt to outlast a planetary disaster by sleeping in stasis, their minds linked in a shared virtual environment. He appears in the second-season Voyager episode The Thaw.
The system gave form to the sleepers' fears as the Clown, who rules the simulation as a ghastly carnival and has already frightened two of them to death. When Harry Kim and B'Elanna Torres enter the system, Viorsa quietly tells them how the stasis controls might be used against their captor.
The Clown reads the scheme in his mind and, after Torres starts to shut the environment down, sends Viorsa to a guillotine. His death persuades Janeway to bargain for the remaining hostages herself.
