One plotline could be Ruby's death leading to a power vacuum. Since she's a powerful and important figure in the RWBY world, her death could cause chaos. Her friends might struggle to fill the void she leaves, both in terms of leadership and combat ability. For instance, they might have to quickly learn to work without her Crescent Rose and her strategic mind.
There could be a plotline where Ruby's death is part of a prophecy. In the RWBY universe, there could be an ancient prophecy that foretells her death, and her friends and allies are trying to prevent it but ultimately fail. This would add an element of fate and inevitability to the story, and her friends would have to come to terms with the fact that they couldn't change the outcome despite their best efforts.
One possible plotline could be that Ruby sacrifices herself to save her friends from an overwhelming enemy. In the heat of battle, she realizes that only by giving up her own life can she ensure the safety of her team. Another could be that she is poisoned by a new and deadly Grimm toxin that slowly weakens her until she passes away, leaving her friends to avenge her.
One possible plotline could be that Ruby's death shatters her team. Weiss might become overly consumed with vengeance, leading her to make hasty and dangerous decisions. Blake could retreat into herself, feeling like she failed to protect Ruby. Yang might struggle with survivor's guilt and question her own strength.

In 'rwby dark ruby fanfic', there might be a plotline where Ruby enters a parallel dark dimension. Here, she finds a distorted version of Remnant where all her friends are either gone or turned evil.

Along the way, she discovers secrets about her own powers and family that she never knew before, which are somehow linked to this dark dimension.
