Her light will live on.

Waligwa portrayed Phionas friend Gloria who teaches her the rules of chess.

Her high school in Uganda remembered Waligwa via Twitter on Saturday.

Fare thee well Nikita Pearl Waligwa, a representative for Gayaza High School captioned a photo of Waligwa.

You were a darling to many and we have lost you to brain tumor at such a tender age.

Nikita was in S.3.

Rest in Perfect Peace dear.

She played Gloria with such vibrancy.

May she truly rest in peace.

May it be well with her soul.

Local reports confirm Waligwa has been laid to rest at her fathers home in Kabojja.
