8778 Border Ambush 8778 Border Ambush is a Knights ' Kingdom II set released in 2004 . The set includes a stone formation and a small defence post with a pit underneath . A rope bridge hanging over a chasm between the two parts . The set also includes a boulder , Santis , a Shadow Knight , and three black scorpion s . Description . The set comprises of two main sections . One section is the side that Santis is at , depicting Morcia . The other is that of a stone structure and represents Ankoria , a dark land and Morcia ' s neighbouring kingdom . The Shadow Knight stands here . The two are connected by a rope bridge . The section of the set that represents the Morcia side is , unlike the other side , a precise and symmetrical structure . It is built on a dark grey base , with a pair of tall white sloping bricks in the front , on either side . Due to a piece with a clip located below the sloping bricks , a long , thin brown piece commonly used as a whip can be attached . Connected to the top of this is a bright green part used as a treetop . Behind the white sloping bricks are light grey ones . On top of these are blue pieces that are connected to the platform on top . The back of the structure has stairs leading up to the platform . Two bricks lines the sides of the platform , with one of them sporting a clip . Attached to the clip is a white pole with a blue flag attached to the top . This setup is on both sides of the platform . In the middle of it is a black and green piece with a part jutting out the back , two studs and a hinge and spring . Santis stands on the studs and a boulder is place directly in front . Using the piece on the back as a handle , one can pull back the piece . When released , the spring and hinge causes it to snap forward , hitting the boulder and sending it flying over the bridge to the other side of the set , hitting the Shadow Knight standing there . The back section of the model widens out at the sides . There are two low dark stone grey walls here , with two black pillars at the back . Three black scorpions are placed inside this . A reddish brown rock face is located at the front . Two black archways are placed on either side , connected the black pillars and the large rock piece . A blue 1x1 brick with a hole in the centre is placed on the rightmost of the black pillars , with a dark stone grey pin with a cone at the tip . A black trapdoor piece is set on top of the setup , covering the pillars , arches and the top of the rock face as a baseplate . The pin keeps it from falling inward , which would drop the Shadow Knight standing there to the area below where the scorpions reside . Next to the black trapdoor , on top of a pair of grey bricks , are two white 2x2 bricks located on either side . Two sloped pillars are on top of these , with a light stone grey archway connected them at the top . The archway has on top of it a 2x1 brick in the center and a 2x1 sloping brick on each side . The three pieces are separated by 1 stud gaps . Also located on top of the sloped pillars are black conical pieces holding transparent orange flame ones , making torches . To the right of this archway is a light stone grey wall that , in turn , is connected to a back wall . This one ends in a rough , imprecise pattern , giving the effect of a crumbling wall . A green plant piece is located on it , above a small vertical slit of a window . Next to this , attached to a black clip piece , is a silver key . Underneath each section is a green baseplate that extends outward , meeting below the bridge . They are connected by another , smaller , piece . On top of this are five black spears spaced unevenly and attached to black cones angled straight up . This forms the chasm . To make the bridge , two parallel green ropes are connected to both sections of the model , stretching over the chasm . The ropes are connected together by the planks , made with a black clip on each side and a reddish brown 1x4 plate on the top and bottom . There are five of these planks on the rope bridge . The set includes two minifigures : Santis and a Shadow Knight . Santis , the protagonist , has a light blue sword , a white shield with a bear emblem , red armor with blue stripes on it and a helmet with a red visor . The Shadow Knight is the set ' s antagonist . This minifigure includes a black torso with red armour printing and a scorpion in the centre and a black helmet and battle axe . Background . When King Mathias of Morcia mysteriously vanished and his advisor , Vladek , took his place , four knights knew something wasn ' t right . They searched the Morcia castle ' s dungeons and found the king , who revealed that Vladek had captured and jailed him and planned to rule over Morcia . The knights then set out to find the Heart of the Magical Shield of Ages , the only other magical force that could challenge Vladek ' s sorcery . On their journey , the four knights came across a rickety bridge over a chasm , with the other side blocked by a Shadow Knight . Upon closer inspection , the knights of Morcia realised he was guarding a key . Two of the companions , Jayko and Rascus , attempted to cross the bridge , to no avail . Santis then tried , lifting a boulder and tossing it at the Shadow Knight , knocking him into the chasm . The knights safely crossed the bridge , acquired the key and continued on their way .
