Changes

However, the empire of the Slann eventually dwindled, the pace of their civilization slowed, and their genetic experiments largely abandoned. They do not seem to have suffered from any physical conflict, wars, or disasters. Rather, the reasons for abandoning their active role in galactic affairs and falling into long dream of indolence and introspection appear to be have been driven by a sudden and drastic change in their race's motivations. With their change in motivations, they have lost interest in material conquest and power. It is perhaps the case that the Slann had discovered something yet unknown to other races, a secret of the universe, a spiritual truth or a supreme metaphysical insight.{{Fn|1b}}

The Slann evolved from amphibian stock, with the traces of their ancestry not being difficult to distinguish. Their hands and feet are webbed and long, their skin is cool and moist, and their heads large with protruding eyes. They are comfortable in water and can breathe in water and other poorly oxygenated environments directly through their skin. Slann can vary wildly in colour, with green and blue being common, yellow being well represented, and with some scatterings of rarer colour morphs, as well as albino or metallic forms. Slann with bright pigmentation are often extroverted, talented or noteworthy in some way. Slann skin is sometimes mottled, striped, or otherwise marked. On some Slann worlds, especially the primitive ones, markings represent tribal divisions. Slann height is fairly constant, with adults reaching 2 metres, with females being slightly larger and bulkier.{{Fn|1b}}
