[quote=@Hael] You're back! If you still want to join, I'll allow it sense you expressed interest earlier, and also because I need someone to distract me from all the shit that went down higher up on the page :lol Still planning on doing the human-like creatures that can do complex mathematics in their minds? I won't allow them to be immortal or disease-immune, as it isn't possible for any organic creature, but I will gladly accept all the rest that you proposed. EDIT: I'm just calling mine "Shield Interference Emitters" xD [/quote] A few Earth-native species are biologically immortal. [i]Turritopsis dohrnii[/i], colloquially known as the "immortal jellyfish", is one such creature. Lobsters are technically biologically immortal, but they eventually succumb to pestilence, fold to predation, or die from sheer exhaustion during a molt attempt during the later stages of their adult lives. Other animals like the three-toed box turtle, certain species of sturgeon fish, or the rougheye rockfish do die from old age, but are negligibly senescent: they do not show any declines in locomotive capacity or reproductive capability as the years pack on. The ring worlder's greatest cultural achievement was finally rendering the Four Horsemen (Famine, Pestilence, War, and Death) effectively null and void by reaching a sufficiently advanced echelon of technological standing. Their nation's fundamental design philosophy was principally predicated on the unorthodox concept of "Gross National Happiness", maximizing this unique measure of national prosperity, and climbing ever forward up the ladder of hedonistic indulgence. Worrying about the flu or where your next meal is going to come from gets in the way of that hedonistic indulgence. Still being constrained by the comparatively petty challenges of 21st century human civilization doesn't make much sense for a people who can pump out interstellar fabrication projects at a whim, traverse the stars at frightening velocities, produce artificial gravity, and wield handheld weapons that can turn a modern 60 ton MBT into a heaping pile of molten slag with one pull of a trigger.
