Anybody else may.
If there are people who still think about joining this RP, they should announce it within the next few days as it will be very difficult to add a sibling in the mid of the RP

Now here's the (very rough) synopsis of the plot.
Evening in the Great Valley, Mama Swimmer tells her sons and daughters that they will have to go on a journey to the "Swimmer Swamps", a region far south-east of the Great Valley. The reason behind this is some sort of "Day of the Swimmers". At the Swamps, they will have to pass several competitions that will test abilities a grown-up Swimmer has to have. Examples may be swimming competitions (both single and team competitions), competitions that'll test their strength (in case they have to defend themselves) and competitions that'll test their social skills needed in adulthood.
The RP will start during the Cold Time (I think that's a good idea since it'd be pretty hot at the Swimmer Swamps during summertime. Besides, I think, if we imagine this place to have a somewhat subtropic climate, it'd be the dry season over there. During the rain season, I imagine such a place to be very muddy and flooded...).
How does this sound? suggesions are welcomed

There will be many dangers of course. Redclaw (or just any random Sharptooth) might be stalking and attacking them, they might get into a severe snowstorm or other severe weather, they might have to cross fast waters, high mountains, violent volcanos - you get the point...
