Uniya mature similarly to humans, and reach physical maturity around age 20.  Once an Uniya reaches physical maturity, aging slows dramatically due to their elven heritage. Uniya have a lifespan that far exceeds Humans and Orcs, but is not quite as long as Elves.  Uniya can live anywhere from 280 years to 500 years, with those that take more strongly after their Elven parent usually living longer. 

Uniya, like many hybrid creatures, tend to be taller than both their parents.  Average heights range from 6ft to 7.5ft, and Uniya who are less than 6ft tall are often considered 'unusually short'.  Your size is Medium. 

Your base walking speed is 30ft

Thanks to your mixed blood, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.
