There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
From her perspective, Western sector looks like a perfect place for a nomad. Afteral there is nobody doing much roaring or scent marking. So it seems like there are no mayor rival prides or dominant coalitions that could threaten her.
In reality, the reason why nobody is doing that is because the area is so crowded with smaller nomadic groups of lions that everybody is keeping their head low to avoid being seen themselves.
She is walking right into a hornets nest.
I don't think she's unaware of what's been happening in the western sector. She most likely knows exactly who is in the western block as she has been hearing those familiar roars for months around that area. You can say it's a risky move but it's a risk worth taking from her aspect probably.
